The old bushi's symbol

 '竜胆'(rindo) was taken as symbol of 源氏(genji) that is Japanese very old Bushi group. Their kamon is also rindo.

This is '笹竜胆紋'(sasa-rindo-mon).sasa is bamboo leaf.It's mixed rindo and sasa.Genji Bushi's symbol mark.

Added Circle '丸ニ竜胆紋'(maru-ni-rindo-mon).

This is omitted bamboo leafs.'二葉竜胆紋'(huta-ba-rindo-mon).At first,we can not recognize this is a kind of rindo model.

'竜胆車紋'(rindo-guruma-mon) is rindo wheel !! It's powerful than original rindo-mon.

'葉隠竜胆紋'(yo-in-rindo-guruma) is one of rindo-guruma.This is a one of design method.Base model is inversed.I don't know historical reason.But I think there were some reasons why the bushi used this mon or had to use.

This is interesting.Rindo and butterfly is united. '竜胆花蝶紋'(rindo-ka-cho-mon).Cool design.
